RAAF air force base at Tindal near Darwin in NT. Transformers 350kva to 2500kva.
Due to the most recent developments in epoxy cast coil production, cooling has now been enhanced with new cooling duct material design . We even use metal cooling ducts to enhance the convection cooling with a conduction component.
Core structure rectangular, windings copper, cooling ducts in between windings outside the core window. This is a finite element computer calculation using ANSYS simulation computer software. Transformer ratings:Input 415V- output…
Ideal for testing laboratories, allows testing at different voltages and frequencies
Tortech makes a range of Isolation transformers from single phase 240v-240v up to 50kVA and 3 phase 415v-415v up to 250kVA. Also isolation transformers for medical & RCD testing purposes.
This is one convenient type of discharge reference source for Partial Discharge applications. It can be used to cross check electrical calibrators for partial discharge.
